65 Days to maturity. Cucumis sativus. Long Green Improved Slicing Cucumber Seeds. Non-GMO, annual, open-pollinated, heirloom, monoecious, slicing cucumber. Suitable for growing in fields, containers (with support), garden plots, raised beds, and greenhouses (with pollinators). Long Green Improved Slicing Cucumber is said to have been introduced in 1870. It surely appears many times in catalogs thereafter. It has stood the test of time because it is a strong, vigorous producer of 10-inch-long cucumbers. Some will exceed 12 inches and more. Excellent for slicing or pick smaller for pickling. Very solid and crisp. ~1,100 seeds/oz.
